7 Claims. (Cl. S12- 152) f This' invention relates to drawer and shell `boxes and has reference to that form or box where the shell is pivoted at the centre upon .av base and `rotation of this shell causes the 5 drawers to .be opened or closed.

v f The object of theA present invention is to provide an improved device of this character and `the invention is concerned primarily with the mechanism by means of which the opening and y'110 closing movement of the drawers is effected.

The invention further comprises a particular method of construction by means of which the arti-cles can be readily assembled from standard parts.

' 15 The present invention comprises an improvementl which consists of drawer operating mechanisrn oi the kind specied comprising a me ohanical movement consisting of a horizontal carrier mounted on a vertical pivot secured to 20 the base of the apparatus, the carrier havingparallel slots or guide ways in which slides a transverse plate xed to a drawer, the said transverse plate having a longitudinal camslot which engages a pinfixed vertically in the base of the g5 apparatus so thatA by turning the carrier about its pivot the transverse plate carrying the drawer will move along the slots or guide ways of the carrier and' so open, the reverse movement closing it.

`30 The carri-er ispreferably provided with two drawers arranged diametrically opposite each other as a set about the vertical pivot and each provided with an identical mechanical movement arranged to open both drawers simultaneously in opposite direction upon rotation of the carrier about its pivot.

Two methods of carrying out the invention are illustrated by the accompanying drawings wherein Figure 1 is a general elevation of one i .40 form of the complete device, Figure 2 a plan of Figure 1, showing in chain lines the position of the drawers or shells, when open. Figure 3 is a sectional elevation on 3 3 Figure 2, and Figure 4 is an inverted plan of part of the device showing the plate to which the drawer is fixed. Figure 5 is a plan of the second method of carrying out the invention, Figure 6 is a plan of the base removed and Figure '7 a sectional elevation on line '7-7 of Figure 5.

In these drawings a is the base of the device, b1 the base plate of the carrier, b2 the top plate of the carrier, these two plates being held the desired distance apart to form a shell element by pillars b3 held between the plates b1 '55 and b2 by rivets b4. The carrier b1 is arranged to rotate on a pivot c having a shoulder or ila-nge cl and fixed in the base plate d, and d1 and d2 are two drawers. Under the bases of the drawers are fixed two sliders el e2 adapted to slide in parallel guide ways or slots b5, h6 39 formed in the carrier plate b1 and are held by the screws e3 and a washer strip c4 inside and drawer dl, to a transverse plate e5, under the carrier plate b1. The transverse plate e5, is provided with a longitudinal cam slot e6 which @5 slides over a xed pin f held in the base a by a nut and bolt f1.

The elements e6 and f comprise a mechanical movement which is brought into operation upon the rotation of the carrier about its pivot to 7@ `open or close the drawer.

Assuming the drawers d1 and d2 in the closed position as indicated in Figure 2, when the carrier b4 is turned about the central pivot c in the direction of the arrows the cam slot e6 ,M oi the transverse plate e5 slides on the pin f and this causes the sliders e1 e2 to move along the slots or guide ways 'b5 in the plate b1 and so push the drawer d1 from under the top plate b2 of the carrier, until it is fully open as indicated by the chain line in Figure 2, that is when the carrier has moved through an angle of about 90. The two drawers dl and d2 being at diametrically opposite positions on the carrier bl operate in opposite directions simultaneousl'y.

In the modication shown in Figures 5 to 'l the guides b5 having cam slots e6 are fixed on the basen and the pin fis fixed by the plate h, strip washer e4 and screws or bolts e3 to the base Q of the drawer dl holding as in the previous eX- ample the sliders el and e2 to the base of the drawer d1, the plate lz being provided with a distance piece h1. The operation is the same as described with reference to Figures 1 to 4.

The tops of these posts or pillars b3 may be provided with ornamental knobs screwed or otherwise applied, the corner ones of which can be used for operating the device. The ends of the shell element bl b2 may be left open or may be closed by panels which will be secured in position between the two plates bl and b2 by means of the posts and knobs aforesaid.

By the foregoing arrangement it will be possible to keep in stock component parts of dif- 05 fering colour or style and make up the articles in any colour scheme that may be desired.

In order to facilitate the extraction of such articles as cigarettes from the drawers an upwardly inclined portion is provided on the bottom of the drawer, and this is preferably arranged to cover the washer strip e4.

What I claim and desire to secure by Letters Patent is:

1. A drawer device of the character described comprising a slidable drawer, a carrier in which the drawer slides, a base plate carrying a pivot on which the carrier isv rotatably mounted, and a mechanical movement operating to open and close the drawer upon the rotation of the carrier about the pivot and consisting of parallel guide ways provided on the carrier, a pair o sliders operating in the guide ways and xed to the drawer, a transverse plate fixed to the sliders, a cam slot in transverse plate, a pin xed vertically in the base plate and enteringr the cam slot.

2. A drawer device of the character described comprising two parallel slidable drawers, a carrier in which both drawers slide in opposite directions, a base plate carrying a pivot on which the carrier is rotatably mounted and a mechanical movement operating to open and close both drawers simultaneously in opposite directions and consisting of two pairs of parallel guide ways provided on the carrier one for each drawer, two pairs of sliders one for each drawer and operating in the guide ways and fixed to the associated drawer, two transverse plates each fixed to a pair of sliders, a cam slot in each transverse plate, two pins xed vertically in the base plate and entering the cam slots respectively.

3. A drawer device of the character described comprising a slidable drawer, two plates fixed together a sufficient distance apart tol form a carrier in which the drawer slides, a base plate carrying a pivot on which the carrier is rotatably mounted, and a mechanical movement operating to open and close the drawer upon the rotation or" the carrier about the pivot and consisting of parallel guide ways provided on the carrier, a pair of sliders operatingr in the guide ways and iixed to the drawer, a transverse plate iixed to the sliders, a cam slot in the transverse plate, a pin xed vertically in the base plate and entering the cam slot.
